How to issue a SOAP request in PHP

Question

I am trying to issue a SOAP request in PHP. I have my service URL, and when I check it in SOAP UI, I can see the following

<application xmlns="http://somenamespace.com">
   <doc xml:lang="en" title="https://someurl.com"/>
   <resources base="https://someurl.com">
      <resource path="sdk/user/session/logon/" id="Logon">
         <doc xml:lang="en" title="Logon"/>
         <param name="ApiKey" type="xs:string" required="false" default="" style="query" xmlns:xs="http://www.w3.org/2001/XMLSchema"/>
         <param name="ApiSecret" type="xs:string" required="false" default="" style="query" xmlns:xs="http://www.w3.org/2001/XMLSchema"/>
         <method name="POST" id="Logon">
            <doc xml:lang="en" title="Logon"/>
            <request>
               <param name="method" type="xs:string" required="true" default="" style="query" xmlns:xs="http://www.w3.org/2001/XMLSchema"/>
               <representation mediaType="application/json"/>
               <representation mediaType="application/xml"/>
               <representation mediaType="text/xml"/>
               <representation mediaType="application/x-www-form-urlencoded"/>
            </request>
            <response status="404 500">
               <representation mediaType="text/html; charset=utf-8" element="html"/>
            </response>
            <response status="">
               <representation mediaType="application/json"/>
               <representation mediaType="application/xml"/>
               <representation mediaType="text/xml"/>
               <representation mediaType="application/x-www-form-urlencoded"/>
            </response>
            <response status="500">
               <representation mediaType="application/vnd.marg.bcsocial.result-v1.9+json; charset=utf-8" element="log:Fault" xmlns:log="https://someurl.com/sdk/user/session/logon"/>
               <representation mediaType="application/vnd.marg.bcsocial.result-v1.9+xml; charset=utf-8" element="web:Result_1" xmlns:web="https://someurl.com/Sdk/WebService"/>
            </response>
            <response status="200">
               <representation mediaType="application/vnd.marg.bcsocial.api.index.options.list-v2.6+xml; charset=utf-8" element="web:ListOfApiIndexOptions_4" xmlns:web="https://someurl.com/Sdk/WebService"/>
               <representation mediaType="" element="data"/>
            </response>
         </method>
      </resource>
   </resources>
</application>

So I am trying to use this to log on. At the moment, I am trying something like the following

public function updateApi(){
    $service_url = 'https://someurl.com/sdk/user/session/logon';
    $curl = curl_init($service_url);
    $curl_post_data = array(
        "ApiKey" => 'somekey',
        "ApiSecret" => 'somesecret',
    );
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $curl_post_data);
    $curl_response = curl_exec($curl);
    curl_close($curl);

    var_dump($curl_response);
}

However, I always receive a fault response that the login has failed. Do I have to call the logon method or something? Really just looking for some advice as to whether I am doing things correctly.

Thanks

Docs for the service you are trying to hit might have explanation of their RESTful services and how to use it. Can you share which API you are trying to hit? Perhaps someone has written wrappers that you could use to simplify your work. — zedfoxus

Unfortunately its a private API, docs are not available unless you log in. Docs only show very basic notes. I have searched and there are no wrappers anywhere. — katie hudson

Is it possible that you're missing the required method parameter in your request? — Val

Try to send your curl_post_data variable as a URL Encoded string. like urlencode('ApiKey=somekey&ApiSecret=somesecret') and secondly try to set the content-type of your request to 'application/x-www-form-urlencoded'' — Santanu Dey

You don't set the Content-Type header telling the format of the content you posted:

curl_setopt($ch, CURLOPT_HTTPHEADER, array(
                      'Content-Type: application/x-www-form-urlencoded'));

Otherwise, from php5 upwards, the usage of http_build_query is recommended:

$curl_post_data = array(
    "ApiKey" => 'somekey',
    "ApiSecret" => 'somesecret',
);

curl_setopt($curl, CURLOPT_POSTFIELDS,
            http_build_query($curl_post_data));

Hope it helps you, Thierry

According the XML you should try to send your curl_post_data variable as a URL Encoded string. like urlencode('ApiKey=somekey&ApiSecret=somesecret') and secondly try to set the content-type of your request to 'application/x-www-form-urlencoded'

$service_url = 'https://someurl.com/sdk/user/session/logon';
$curl = curl_init($service_url);
$headers = ["Content-Type: application/json"];  // or other supported media type
$curl_post_data = array(
    "ApiKey" => 'somekey',
    "ApiSecret" => 'somesecret',
);

curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $curl_post_data);
curl_setopt($rest, CURLOPT_HTTPHEADER,$headers);  
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);  
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);  
$curl_response = curl_exec($curl);
curl_close($curl);
